Method of making cartons



Feb. 16, 1932. J. WAGNER 1,845,45fi v METHOl OF MAKING CARTONS Filed Aug. 1; 1931 lNVE-INTOR Patented Feb. 16, 1932 1 UNITED STATES PATENT OFFICE JO SHUA WAGNER,

OF BROOKLYN, NEW YORK, ASSIGNOR TO DIAGONAL CORRUGATED PATENT CORPORATION, OF BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK METHOD OF MAKING CARTONS Application filed August 1, 1931. Serial No. 554A56.

The invention relates to cartons and carton blanks such as are made from corrugated paper board or like material, and aims primarily to provide an improved method of cutting the blanks from continuous corrugated paper board sheets, such as are formed by corrugating machines of the type 1n common use. a

In the drawings- Fig. l is a plan view of a length of corrugated paper board bearing lines to indicate how the carton blank may be cut therefrom, creased and slotted in accordance with the present invention.

Fig. 2 shows such a blank folded into a flat form in which cartons of the type here involved are usually stored for use.

Fig. 3 is a perspective view showing the blank in carton form.

The invention is illustrated as applied to a corrugated paper board sheet 1 which may be understood as having the usual facing sheets and corrugated liner. The corrugations of the liner may run transversely of the sheet 1 as is the case with the continuous sheet formed by the types of corrugating machines in common use, or if desired the corrugations may run at an angle ofabout45" to the side edges 2 of sheet 1, as indicated in Fig. 1 by the dotted lines 3.

In accordance with the present invention, the sheet 1 is out along diagonal lines 4 which run preferably at an angle of about 45 to the side edges 2 of the sheet, thisoperation being preferably performed by a cut-off knife such as is usually operated periodically at the deliveryend of a corrugatlng machine to cut the blanks to proper size.

The blank thus formed is scored along the lines 5 extending parallel to the side edges 2 of sheet 1, and scored and slotted respectively along the lines 6 and 7 which extend perpendioular to the side edges 2 and score lines 5, in case a carton is desired of the type known in the'trade as the standard slotted carton, which has four sides and flaps forming two end faces.

In the form of blank shown 1n Flg. 1, however, certain of the parts of the blank which are to form the sides of the carton, as denoted byiiumeral to form other sides of the carton will be complementary fractions of a receptacle, as indlcated by the numerals 8a; and likewise certam of the parts of the blank which are to form end flaps will be full receptacles as indlcated by numeral 9, and certain other parts which are to form end flaps will be complementary fractional parts of a receptacle as lndicated by numerals 9a.

As will be noted from Figs. 2 and 3, the blank is so formed and folded that the joint between the sides is constituted by the diagonal lines of cut 4, while the side edges 2 of the paper board sheet constitute the ends of the flaps 9 and 9a. In accordance with this method of forming the blank the width of sheet 1 is selected in accordance with the of carton (and end flaps) to be made,

height and the length and width of the carton determines the distance between the diagonal lines of cut 4. Particularly for long cartons, this method of cutting is advantageous in that the long dimension of the blank becomes parallel to the length of the continuous sheet 1, allowing the cartons to be made without requiring sheets of undue width.

The joint 4 of the carton may be secured in any desired manner, for instance, by the use of a strip of adhesive 10 as shown in Figs. 2 and 3.

When blanks are out according to the present invention from corrugated paper board of the type in most common use, i. e. having the corrugations running transversely of the sheet, the corrugations will run either perpendicular or parallel to the various edges of the carton, as in the usual standard slotted carton now in common useghowever, if the corrugations are formed diagonally of the sheet as indicated at 3 in Fig. 1, and the lines of cut 4 are directed transversely of these corrugations, the corrugations in the completed carton will run at an angle to the various edges of the carton, as in my prior Patent No. 1,620,17 i, dated March 8, 1927. The same would be true if the lines of cut 4 ran parallel to the diagonal corrugations 3,

8, will be full receptacles, where- I as certain other parts of the blank which are although in this case the corrugations would run arallel to the joint at 4 of the carton.

hile a specific mode of carrying out the inventionhas been described, it shouldbe understood that changes may be made therein without departing from its principles within the scope of the appendedclaims,

I claim:

1. The method of making cartons which comprises cutting a continuous sheet of corrugated paper board along parallel lines oblique to the side edges of the sheet, scoring the blank thus formed along lines substantially parallel to said side edges, and slotting 5 and scoring the blank along lines substantially perpendicular to said side edges and folding the blank to form a joint between said first mentioned lines of cut.

' 2. The method of making cartons from a go continuous sheet of corrugated paper board having the corrugations running oblique to the side edges of the sheet,'which comprises cutting said sheet along parallel lines running oblique to said side edges and running transversely to said corrugations, scoring the blank thus formed along lines substantially parallel to said side edges and slotting and scoring the blank along lines substantially perpendicular to said side edges and folding the blank to form a joint between the first mentioned lines ofcut.

3. The method of making cartons from a continuous sheet of corrugated paper board having corrugations running oblique to the 85 side edges of the sheet, which comprises cutting the sheet along parallel lines oblique to its side edges, scoring the blank thus formed along lines substantially parallel to said side edges, slotting and scoring the blank along lines substantially perpendicular to said side edges, and folding the blank to form a joint between said first mentioned lines of cut.

In testimony whereof I have signed my name to this specification.

JOSHUA WAGNER.
